(C)after the threshold in Section 3.2(d)(iii)(B) has been met, ***** percent ***** of Net Sales.

For the avoidance of doubt, Licensor shall be prohibited from Developing or Commercializing a product or products utilizing any Development Candidate until no Development Candidate directed to the same Collaboration Target or TNF-α Target is being Developed or Commercialized for Licensee.

3.3 Failure to Develop Following Option Exercise.

(a)Collaboration Target. If, with respect to a given Collaboration Target, there is any Collaboration Development Candidate for which Licensee provides notice to Licensor that Licensee decides not to continue to Develop and Commercialize following Option exercise and that Licensee reverts its rights relating to such Collaboration Target (including all related Collaboration Development Candidates) to Licensor, then all rights to such Collaboration Target (including all related Collaboration Development Candidates) will revert to Licensor along with any intellectual property developed by Licensee covering such Collaboration Development Candidates or any method of use or method of manufacture of such Collaboration Development Candidates; provided, however, that such rights will not revert if Licensee’s notice of its decision not to continue to Develop and Commercialize a Collaboration Development Candidate following Option exercise states that Licensee wishes to continue to Develop new Collaboration Development Candidates for such Collaboration Target, in which case, subject to the limitations on the obligations of Licensor as set forth in Section 2.5, Licensor will continue to

perform such Development, at Licensee’s expense, and Licensee shall retain exclusivity of such Collaboration Target.

(b)AST-005. If Licensee provides notice to Licensor that Licensee decides not to continue to Develop and Commercialize AST-005 following Option exercise and that Licensee reverts its rights relating to TNF-α Target (including all related TNF-α Development Candidates, including AST-005) to Licensor, then all rights to TNF-α Target (including all related TNF-α Target Development Candidates, including AST-005) will revert to Licensor along with any intellectual property developed by Licensee covering such TNF-α Development Candidates or any method of use or method of manufacture of such TNF-α Target Development Candidates; provided, however, that such rights will not revert if Licensee’s notice of its decision not to continue to Develop and Commercialize AST-005 following Option exercise states that Licensee wishes to continue to Develop new TNF-α Target Development Candidates for TNF-α Target, in which case, subject to the limitations on the obligations of Licensor as set forth in Section 2.5, Licensor will continue to perform such Development, at Licensee’s expense, and Licensee shall retain exclusivity of TNF-α Target.

(c)Royalties. If there is any reversion of rights to Licensor pursuant to Sections 2.10 (by way of 3.3(a) applying mutatis mutandis), 3.3(a) or 3.3(b) and Licensor alone or with a Third Party thereafter Develops and Commercializes a product or products utilizing such Development Candidate for the same Indication or otherwise in a similar manner as set forth in the “Collaboration Research Plan” for such Development Candidate, then Licensor will pay Licensee a royalty of (i) ***** percent ***** of Net Sales if such Development Candidate has not started a Phase 3 Study at the time of cessation of Development, and (ii) ***** percent ***** of Net Sales if such Development Candidate has started a Phase 3 Study at the time of cessation of Development. For the avoidance of doubt, Licensor alone or with a Third Party shall be prohibited from Developing or Commercializing a product or products utilizing a Development Candidate until Licensee provides notice to Licensor that Licensee decides not to continue to Develop and Commercialize such Development Candidate following Option exercise and that Licensee reverts its rights to such Collaboration Target or TNF-α Target pursuant to Sections 2.10 (by way of 3.3(a) applying mutatis mutandis), 3.3(a) or 3.3(b).

Notwithstanding the foregoing, a Party making a payment pursuant to this Agreement shall not be deemed to have made a late payment, and no interest shall be due pursuant to this Section 8.7, if the payment is not made by the due date as a result of the Payee’s efforts to reduce or eliminate a tax applicable to such payment pursuant to Section 8.10(c), provided the paying Party makes the required payment (net of applicable withholding taxes) as soon as practicable after the tax issue is resolved.

8.8 Records. Each Party will keep (and will ensure that its Affiliates and sublicensees keep) such records as are required to determine, in accordance with U.S. generally accepted accounting principles or international financial reporting standards, as applicable, and this Agreement, the sums or credits due under this Agreement, including Development Costs and Net Sales. Such Party will retain all such books, records and accounts until the later of (a) ***** after the end of the period to which such books, records and accounts pertain and (b) the expiration of the applicable tax statute of limitations (or any extensions thereof), or for such longer period as may be required by Laws. Each Party will require its sublicensees to provide to it a report detailing the foregoing expenses and calculations incurred or made by such sublicensee, which report will be made available to the other Party in connection with any audit conducted by such other Party pursuant to Section 8.9.

8.9 Audits. Each Party may have an independent top four certified public accountant, reasonably acceptable to the audited Party, have access during normal business hours, and upon reasonable prior written notice, to examine only those records of the audited Party (and its Affiliates and sublicensees) as may be reasonably necessary to determine, with respect to any Calendar Year ending not more than ***** before such Party’s request, the correctness or completeness of any report or payment made under this Agreement; provided, however, the audited Party shall not be required to provide, and neither the auditing Party nor the independent certified public accountant shall be entitled to review, the tax returns or tax records of the audited Party or those of its Affiliates and sublicensees. The foregoing right of review may be exercised only ***** per ***** and only ***** with respect to each such periodic report and payment, unless such audit report concludes (i) or (ii) below, in which case there shall be no limit of how many times such right may be exercised during such period. Reports of the results of any such examination will be (a) limited to details of any discrepancies in the audited Party’s records relating to Product together with an explanation of the discrepancy and the circumstances giving rise to the discrepancy (b) made available to both Parties and (c) subject to Article 12. If the audit report concludes that (i) additional amounts were owed by the audited Party, the audited Party will pay the additional amounts, with interest from the date originally due as provided in Section 8.7 or (ii) excess payments were made by the audited Party, the auditing Party will reimburse such excess payments, with interest from the date when the original payment was made, in either case ((i) or (ii)), within ***** after the date on which such audit report is delivered to both Parties. The Party requesting the audit will bear the full cost of the performance of any such audit, unless such audit, which covers the entire Calendar Year, discloses a variance to the detriment of the auditing Party of more than ***** from the amount of the original report, royalty or payment calculation, in which case the audited Party will bear the full cost of the performance of such audit. The results of such audit will be final, absent manifest error.

8.10 Taxes.

(a)Taxes on Income. Each Party will pay all taxes imposed on its share of income arising directly or indirectly from the efforts of, or the receipt of any payment by, such Party under this Agreement.

(b)Tax Withholding. If any taxes are required to be withheld by a Party with respect to an amount payable to the other Party, such Party will: (a) withhold such taxes from the payment made to the other Party; (b) timely pay the withheld taxes to the proper taxing authority; (c) send proof of payment to the other Party; and (d) reasonably assist the other Party in its efforts to obtain a refund of or credit for such tax payment in accordance with Section 8.10(c). Any amount actually withheld and remitted by a Party to a taxing authority pursuant to this Section 8.10(b) will be treated for all purposes of this Agreement as paid to the other Party. If a Party makes a payment without deduction for tax withholding and an amount of tax should have been withheld from such payment, the Party that made such payment shall be entitled to recover the underwithheld tax by an additional withholding from any amount payable to the

other Party under this Agreement. No amount shall be withheld, or a reduced amount shall be withheld, as applicable, if, in accordance with Section 8.10(c), a Party that is entitled to a payment timely furnishes the other Party with the necessary tax forms and other documents prescribed by Laws, which shall be in a form reasonably satisfactory to the Party receiving the documents, identifying that the relevant payment is exempt from tax or subject to a reduced tax rate.

(c)Tax Cooperation. The Parties agree to cooperate with one another and use reasonable efforts to reduce or eliminate tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by one Party to the other Party under this Agreement. The Party entitled to a payment will provide the paying Party with any tax forms that may be reasonably necessary in order for the paying Party not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Each Party will provide the other with reasonable assistance to enable the recovery, as permitted by Law, of withholding taxes, value added taxes, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or value added tax.

8.11 Equity Investment.

(a)Equity Purchase. At any time between the Effective Date and the earlier to occur of (i) *****, or (ii) *****, if Licensor sells any of its senior preferred stock having liquidation and other rights equal or senior to any other preferred stock issued to date, Licensee and/or its Affiliates will purchase from Licensor and Licensor will sell ***** Dollars ***** of such preferred stock at a purchase price based upon a fully-diluted pre-money valuation of ***** Dollars ***** or such lesser pre-money valuation determined at such preferred stock financing, on the same terms and conditions (other than with respect to the aforementioned valuation and the Board rights as set forth in Section 8.11(b) of this Agreement) that apply to the sale of such number of shares of preferred stock.

(b)Observer.

For clarity, if Licensee appoints a designee to the Board but then that designee later resigns, Licensee shall have the right to designate an Observer. The Observer will initially be *****, who may be replaced upon written notice by Licensee to the Licensor by a future designee of the Licensee reasonably acceptable to the Board. Licensor will provide the Observer by way of example and without limitation, all notices, minutes, consents, management presentations, strategic planning materials, scientific reports, routine financial reports, and other material, financial or otherwise, that the Licensor provides to the Board at the same time that such notices and materials are provided to the Board, including, for the avoidance of doubt, for

ad hoc meetings; provided that the Observer enter into the Licensor’s form of confidentiality agreement as mutually agreed to by Licensee. Licensee understands and agrees that the Observer may not attend any portion of a Board meeting or receive certain Board materials if, on the advice of Licensor’s counsel, Observer’s participation or receipt of information (i) would create an actual conflict of interest or (ii) could reasonably be expected to compromise attorney-client privilege with respect to a dispute between the Licensor and a Third Party. Licensee understands and agrees that the Observer may not attend any portion of a Board meeting or receive certain Board materials if, on the advice of Licensor’s counsel, Observer’s participation or receipt of information would create an actual conflict of interest.

(c)Board Member. Licensor agrees that it shall appoint, upon Licensee’s request, a designee of the Licensee to the Board within the later of (x) ***** after the closing of the equity purchase pursuant to Section 8.11(a) or (y) Licensee’s request. Such designee may remain on the Board until the earlier of (i) *****, (ii) the termination or expiration of this Agreement, or (iii) the date Licensee and its Affiliates no longer own the preferred stock purchased pursuant to Section 8.11(a) or any of the shares issued upon conversion thereof. Licensee understands and agrees that the designee of the Licensee may not attend any portion of a Board meeting or receive certain Board materials if, on the advice of Licensor’s counsel, such designee’s participation or receipt of information would create an actual conflict of interest. The appointment of the Licensee’s designee to the Board will be subject to the same terms and conditions as Licensor’s existing Board members, with the exception that no cash, stock, stock options or other compensation will be provided to Licensee’s designee to the Board.

(d)SAB Member. As of the Effective Date, Licensor hereby agrees that Licensee may designate in writing a representative to become a member of Licensor’s Scientific Advisory Board (“SAB Member”), as reasonable acceptable to the Board and who may be replaced upon written notice by Licensee to the Licensor by a future designee of the Licensee reasonably acceptable to the Board. The SAB member will initially be *****. The appointment of the SAB Member will be subject to the same terms and conditions as Licensor’s existing SAB members, with the exception that no cash, stock, stock options or other compensation will be provided to such SAB Member.

(e)Notwithstanding anything to the contrary stated in this Sections 8.11, however, Licensor reserves the right to exclude the Observer and SAB Member from access to any materials or meeting or any portion of any materials or meeting if the Board determines, upon advice of counsel, that such exclusion is reasonably necessary to preserve the attorney-client privilege, to protect confidential, proprietary or competitive information, to avoid, mitigate or otherwise address any actual, potential or perceived conflict of interest, is necessary to discharge the Board’s fiduciary duties and/or for other similar reasons. Licensee agrees, and the Observer and SAB Member will agree, to hold in confidence and trust, and not use or disclose, any confidential or proprietary information of the Licensor or any Third Party provided to or learned by the Licensee, Observer and/or SAB Member in connection with Licensee’s rights under Sections 8.11(b) and (c) unless such information (a) is known or becomes known to the

public in general (other than as a result of a breach of Sections 8.11(b) or (c) by Licensee, Observer or SAB Member, as applicable), (b) is or has been independently developed or conceived by or on behalf of Licensee, its Affiliates, Observer or SAB Member without use of such information, or (c) is or has been made known or disclosed to the Licensee, its Affiliates, Observer or SAB Member by a Third Party without a breach of any obligations of confidentiality such Third Party may have to Licensor; provided, however, that Licensee may disclose such information (i) to its Affiliates and its and their respective attorneys, accountants, consultants, lenders, insurers, financial advisors and other professionals to the extent necessary to obtain their services in connection with monitoring this Agreement and its and/or its Affiliates’ investment in Licensor pursuant to Section 8.11(a), provided that each such person is bound by obligations of confidentiality and non-use no less stringent than those set forth herein, or (ii) as otherwise required by law, judicial or regulatory process. If reasonably requested by Licensor, the Observer and SAB Member will execute a confidentiality agreement in a mutually agreed upon form.

ARTICLE 9

INTELLECTUAL PROPERTY MATTERS

9.1 Ownership of Inventions. Licensor will own any inventions, whether or not patentable, invented solely by its own employees, agents, or independent contractors in the course of conducting its activities under this Agreement, together with all intellectual property rights therein (“Licensor Inventions”). Licensee will own any inventions, whether or not patentable, invented solely by its own employees, agents, or independent contractors in the course of conducting its activities under this Agreement, together with all intellectual property rights therein (“Licensee Inventions”). The Parties will jointly own any inventions that are invented jointly by employees, agents, or independent contractors of each Party in the course of performing activities under this Agreement, together with all intellectual property rights therein (“Joint Inventions”). Licensee agrees to assign and does hereby assign to Licensor all of Licensee’s rights, title and interest in and to any Licensee Inventions and Joint Inventions that are directed solely to the SNA Platform Technology (“SNA Platform Technology Inventions”). Inventorship as between the Parties will be determined in accordance with the law of inventorship of the U.S. Except to the extent either Party is restricted by the licenses granted to the other Party under this Agreement or the other terms of this Agreement, each Party may practice and exploit the Joint Inventions and Joint Patents without the duty of accounting or seeking consent from the other Party.

9.2 Disclosure of Inventions; Patent Strategy Consultation. Each Party will promptly disclose to the other Party all inventions (whether Licensor Inventions, Licensee Inventions or Joint Inventions), including any invention disclosures, or other similar documents, submitted to it by its employees, agents or independent contractors describing inventions that are either Licensor Inventions, Licensee Inventions or Joint Inventions, and all material Information

relating to such inventions to the extent necessary or useful for the preparation, filing and maintenance of any Patent, and the determination of inventorship, with respect to such invention.

9.3 Prosecution of Patents.

(a)Subject to Section 9.3(b), as between the Parties, and after the Option exercise for a given Development Candidate, Licensee may prepare, file, prosecute and maintain patents in any and all jurisdictions worldwide covering Licensee Inventions, Licensor Inventions and Joint Inventions solely for patents which include claims directed specifically to any Collaboration Development Candidates and do not include any claims covering any SNA Platform Technology Inventions (collectively, the “Licensee Prosecuted Patents”). As between the Parties, Licensee will bear and be solely responsible for all costs incurred after the Effective Date only in connection with the preparation, filing, prosecution or maintenance of any Licensee Prosecuted Patent that it chooses to prepare, file, prosecute or maintain in the Territory. Before any substantive prosecution filing, Licensee will provide Licensor with a reasonable opportunity to review and comment on such prosecution efforts regarding the Licensee Prosecuted Patents as follows: Licensee will promptly provide Licensor with copies of all material communications from any patent authority regarding the Licensee Prosecuted Patents, and will provide Licensor, for its review and comment, with drafts of any material filings or responses to be made to such patent authorities in a reasonable amount of time in advance of submitting such filings or responses. Licensee will consider in good faith any reasonable comments thereto provided by Licensor in connection with the prosecution of the Licensee Prosecuted Patents. Each Party will provide the other Party all reasonable assistance and cooperation in the patent prosecution efforts provided in this Section 9.3(a), including executing any other required documents or instruments for such prosecution. Notwithstanding the foregoing, (i) Licensor will be responsible for preparing, filing, prosecuting and maintaining any patents covering any Licensor Inventions and Joint Inventions prior to the Option exercise, including any costs associated therewith; (ii) Licensor will be responsible for preparing, filing, prosecuting and maintaining any patents covering SNA Platform Technology Inventions that are Licensor Inventions or Joint Inventions, including any costs associated therewith; and (iii) Licensor will be responsible for preparing, filing, prosecuting and maintaining any patents covering SNA Platform Technology Inventions that are Licensee Inventions, and all costs associated therewith, regardless of the Option exercise. Before any substantive prosecution filing for patents covering SNA Platform Technology Inventions by Licensor, Licensor will provide Licensee reasonable opportunity to review and comment with respect to such patents. Before any filing for patents covering SNA Platform Technology Inventions invented by Licensee, Licensor will provide Licensee reasonable opportunity to review and comment with respect to such patent filings.

(b)f Licensee decides not to prepare or file, or to abandon, any Licensee Prosecuted Patent or not to apply for an extension of any Licensee Prosecuted Patent, including a supplementary protection certificate or equivalent thereof, anywhere in the Territory, Licensee will promptly notify Licensor and Licensor may assume Licensee’s rights and responsibilities under this Section 9.3 with respect to such Licensee Prosecuted Patent, and in connection with

assuming such rights and responsibilities, including responsibility for costs, Licensor may prepare, file, prosecute, maintain or apply for any extension (including a supplementary protection certificate or equivalent thereof) and Licensor will thereafter control the prosecution and maintenance of such Licensee Prosecuted Patent in the Territory.

9.4 Patent Enforcement in the Territory.

(a)Notification. If either Party become aware of any existing or threatened infringement of any of the Licensor Patents or Joint Patents in the Field in the Territory by a Third Party (“Territory Infringement”), such Party will promptly notify the other Party in writing to that effect and the Parties will consult with each other regarding any actions to be taken with respect to such Territory Infringement.

(b)Enforcement Rights. For any Territory Infringement, each Party will share with the other Party all Information available to it regarding such actual or alleged infringement. As between the Parties, Licensee may bring an appropriate suit or other action against any person or entity engaged in any such Territory Infringement which infringes any patent that includes claims directed specifically to any Collaboration Development Candidates, at Licensee’s cost and expense. If Licensee fails to commence a suit to enforce the applicable Joint Patents or Licensor Patents against such Territory Infringement or to settle or otherwise secure the abatement of such Territory Infringement within such period, then Licensor may commence a suit or take action to enforce such Joint Patents or Licensor Patents against such Territory Infringement at its own cost and expense. In this case, Licensee will take appropriate actions to enable Licensor to commence a suit or take the actions set forth in the preceding sentence.

(c)Collaboration. Each Party will provide to the enforcing Party reasonable assistance in such enforcement, at such enforcing Party’s request and expense, including executing all necessary and proper documents and using best efforts if required to establish and maintain standing to join such action as a party plaintiff if required by Law to pursue such action. The enforcing Party will keep the other Party regularly informed of the status and progress of such enforcement efforts, will reasonably consider the other Party’s comments on any such efforts, and will seek consent of the other Party in any important aspects of such enforcement, including determination of litigation strategy and filing of material papers to the competent court, which consent will not be unreasonably withheld, conditioned or delayed. The non-enforcing Party may obtain separate representation in such matter by counsel of its own choice and at its own expense, but such Party will at all times cooperate fully with the enforcing Party.

(d)Settlement. Licensor will not settle any claim, suit or action that it brought under Section 9.4(b) in any manner that would negatively impact the applicable Licensor Patents or Joint Patents or that would limit or restrict the ability of Licensee to Develop, make, have made or Commercialize Products anywhere in the Territory in the Field, without the prior written consent of Licensee, which consent will not be unreasonably withheld, conditioned or delayed. Nothing in this Article 9 requires Licensee to consent to any settlement that is

reasonably anticipated by Licensee to have a substantially adverse impact upon any Licensor Patent or Joint Patent in the Territory, or to the Development, manufacture or Commercialization of Products in the Territory in the Field.

(e)Expenses and Recoveries. The enforcing Party bringing a claim, suit, or action under Section 9.4(b) will pay for any expenses incurred by such Party as a result of such claim, suit, or action. If such Party recovers monetary damages in such claim, suit or action, such recovery will be allocated first to the reimbursement of any expenses incurred by the Parties in such litigation, and any remaining amounts will be retained by the Party bringing suit.

9.5 Infringement of Third Party Rights in the Territory.

(a)Prior to the completion of the first Phase 3 Study under this Agreement, the Parties will agree on and enter into a common interest agreement.

(b)Subject to Article 12, if a Product used or sold by Licensee, its Affiliates or Sublicensees becomes the subject of a Third Party’s claim or assertion of infringement of a Patent granted by a jurisdiction within the Territory (each such claim or assertion a “Third Party Claim”), Licensee will promptly notify Licensor and the Parties will work toward their shared, mutual interest in the outcome of such potential dispute, and thereafter, the Parties will promptly meet to consider the Third Party Claim and the appropriate course of action. Licensee will defend any such Third Party Claim that pertains solely to patents that include claims directed specifically to any Collaboration Development Candidates, at Licensee’s cost and expense; provided that the provisions of Section 9.4 govern the right of Licensee to assert a counterclaim of infringement of any Licensor Patents or Joint Patents.

(c)If, during the Term, a Third Party Claim that pertains solely to patents that include claims directed specifically to any Collaboration Development Candidates arises which Licensee deems it necessary to defend, Licensee may reduce, to offset the costs and expenses incurred or otherwise expended by Licensee in connection with the defense or settlement of such Third Party Claim, royalties otherwise due to Licensor under Section 8.4 by up to ***** percent ***** (such royalty rates may be further reduced as set forth herein).

9.6 Patent Marking. Licensee and its Affiliates and Sublicensees will ▇▇▇▇ any Product marketed and sold by Licensee or its Affiliates or Sublicensee hereunder with appropriate patent numbers or indicia; provided, however, that Licensee will only be required to so ▇▇▇▇ such Product to the extent such markings or such notices would affect recoveries of damages or equitable remedies available under Laws with respect to infringement of Patents in the Territory.

9.7 Packaging; Trademarks. Licensee will design all final commercial packaging and labeling of Product for use in the Territory, and may select the brand name of Products in the Territory and register any trademarks resulting therefrom at Licensee’s sole cost and expense.

Licensor will, at its sole expense, defend, indemnify, and hold Licensee and its Affiliates and their respective officers, directors, shareholders or owners, employees, and agents (the “Licensee Indemnitees”) harmless from and against any and all Third Party claims, suits, proceedings, damages, losses, liabilities, taxes, costs, expenses (including court costs and reasonable attorneys’ fees and expenses) and recoveries (collectively, “Claims”) to the extent that such Claims arise out of, are based on, or result from (a) the conduct by Licensor or any of its Affiliates or Third Parties of Development activities as part of the Collaboration Research Program, (b) the breach of any of Licensor’s obligations under this Agreement, including Licensor’s representations and warranties, covenants and agreements, (c) the breach or default of any Loan Facility or Head License Agreements by Licensor, or (d) the willful misconduct or negligent acts of Licensor, its Affiliates, or the officers, directors, employees, or agents of Licensor or its Affiliates. The foregoing indemnity obligation will not apply (i) to the extent that (x) the Licensee Indemnitees fail to comply with the indemnification procedures set forth in Section 11.3 and Licensor’s defense of the relevant Claims is prejudiced by such failure or (y) such Claims arise out of or result from the gross negligence or willful misconduct of Licensee or its Affiliates, or any related breach by Licensee of its representations, warranties or covenants or any other obligation of Licensee hereunder; or (ii) to Claims for which Licensee has an obligation to indemnify Licensor pursuant to Section 11.2, as to which Claims each Party will indemnify the other to the extent of its respective liability for such Claims.

11.2 Indemnification by Licensee. Licensee will, at its sole expense, defend, indemnify, and hold Licensor and its Affiliates and their respective officers, directors,

shareholders or owners, employees, and agents (the “Licensor Indemnitees”) harmless from and against any and all Claims to the extent that such Claims arise out of, are based on, or result from (a) Development or Commercialization of any Development Candidates or Products by or on behalf of Licensee or its Affiliates or its or their Sublicensees, (b) the breach of any of Licensee’s obligations under this Agreement, including Licensee’s representations and warranties, covenants and agreements or (c) the willful misconduct or negligent acts of Licensee, its Affiliates, or the officers, directors, employees, or agents of Licensee or its Affiliates.

Each Party agrees that, during the Term and for a period of ***** thereafter, it and its Affiliates will keep confidential and will not publish or otherwise disclose and will not use for any purpose other than as provided for in this Agreement (which includes the exercise of any rights or the performance of any obligations hereunder or thereunder) any Confidential Information furnished to it or its Affiliate by the other Party or its Affiliate pursuant to this Agreement, except to the extent expressly authorized by this Agreement or as otherwise agreed to in writing by the Parties. The foregoing confidentiality and non-use obligations do not apply to any portion of the other Party’s Confidential Information that the receiving Party can demonstrate by competent written proof:

(a) was already known to the receiving Party or its Affiliate, other than under an obligation of confidentiality, at the time of disclosure by the other Party or its Affiliate;

(b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party or its Affiliate;

(e) was independently discovered or developed by the receiving Party or its Affiliate without access to or aid, application or use of the other Party’s Confidential Information, as evidenced by a contemporaneous writing.

12.2 Authorized Disclosure. Notwithstanding the obligations set forth in Section 12.1, a Party or its Affiliate may disclose the other Party’s Confidential Information and the terms of this Agreement to the extent:

(b)such disclosure is reasonably necessary to its officers, directors, employees, agents, consultants, contractors, licensees, sublicensees, attorneys, accountants, lenders, insurers or licensors on a need-to-know basis for the sole purpose of performing its obligations or exercising its rights under this Agreement; provided that in each case, the disclosees are bound by obligations of confidentiality and non-use no less stringent than those contained in this Agreement;

(c)such disclosure is reasonably necessary to any bona fide potential or actual investor, acquiror, merger partner, or other financial or commercial partner for the sole purpose of evaluating an actual or potential investment, acquisition or other business relationship; provided that in each case, the disclosees are bound by written obligations of confidentiality and non-use having a minimum term of *****; or

(d)such disclosure is reasonably necessary to comply with Laws, including regulations promulgated by applicable security exchanges, court order, administrative subpoena or other order.

Notwithstanding the foregoing, if a Party or its Affiliate is required to make a disclosure of the other Party’s Confidential Information pursuant to Section 12.2(a) or 12.2(d), such Party will promptly notify the other Party of such required disclosure and, upon the other Party’s request, such Party and its Affiliates will use reasonable efforts to obtain, or to assist the other Party in obtaining, a protective order preventing or limiting the required disclosure.

Neither Party nor their Affiliates will submit for publication, publish or present a Publication without the opportunity for prior review by the other Party, except to the extent required by Laws. A Party seeking, or whose Affiliate is seeking, to submit, publish or present a Publication will provide the other Party the opportunity to review and comment on the proposed Publication at least fifteen (15) days before its intended submission for publication or presentation. The other Party will provide the Party seeking, or whose Affiliate is seeking, to publish or present with its comments in writing, if any, within ten (10) days after receipt of such proposed Publication. The Party seeking, or whose Affiliate is seeking, to publish or present will consider in good faith any comments thereto provided by the other Party and will comply with the other Party’s request to remove any and all of such other Party’s Confidential Information from the proposed Publication. In addition, the Party seeking, or whose Affiliate is seeking, to publish or present will delay the submission for a period of up to thirty (30) days if the other Party can demonstrate reasonable need for such delay to prepare and file a patent application for which it has prosecution control pursuant to this Agreement. If the other Party fails to provide its comments to the Party seeking, or whose Affiliate is seeking, to publish or present within such ten (10)-day

period, such other Party will be deemed not to have any comments, and the Party seeking, or whose Affiliate is seeking, to publish or present may submit for publication or present in accordance with this Section 12.3 after the fifteen (15)-day period has elapsed. The Party seeking, or whose Affiliate is seeking, to publish or present will provide the other Party a copy of the manuscript, abstract or presentation at the time of the submission or presentation, as applicable. Each Party agrees to acknowledge the contributions of the other Party and its Affiliates and their employees in all publications, as scientifically appropriate. Further, Licensor will provide to Licensee all publications, and other forms of public disclosure such as abstracts and presentations, of results of studies carried out to the extent it relates to the SNA Platform Technology and is not protected by a confidentiality agreement with a Third Party.

In relation to the other Party’s review of such an announcement, such other Party may make specific, reasonable comments on such proposed press release within the prescribed time for commentary, but will not withhold, condition, or delay its consent to disclosure of the

information that the relevant milestone or Regulatory Approval has been achieved or material event has occurred. Neither Party nor their Affiliates are required to seek the permission of the other Party to repeat any information regarding the terms of this Agreement that has already been publicly disclosed by such Party or its Affiliate, or by the other Party or its Affiliate, in accordance with this Section 12.4, if such information remains accurate as of such time.

If any such obligations conflict with the obligations set forth in any prior confidentiality agreements, then the other Party and its Affiliates and disclosees will comply with the more stringent provision.

12.6 Return of Confidential Information. Except as otherwise set forth in this Agreement, upon termination of this Agreement, the receiving Party will promptly return all of the disclosing Party’s Confidential Information, including all reproductions and copies thereof in any medium, except that the receiving Party may retain a reasonable number of archival copies as may be required by law or its standard document retention policies.

12.8 Exclusive Property.

13.7 Termination for Non-Fundamental Breach.

(a)Termination Upon Written Notice. Each Non-Breaching Party may terminate this Agreement in its entirety or on a country-by-country basis immediately upon written notice to the Breaching Party if the Breaching Party commits a Non-Fundamental Breach and, after receiving written notice identifying such Non-Fundamental Breach in reasonable detail (a “Non-Fundamental Default Notice”), fails to cure such Non-Fundamental Breach within ***** after delivery of the Non-Fundamental Default Notice (or within ***** after delivery of the Non-Fundamental Default Notice if such Non-Fundamental Breach is solely based on the Breaching Party’s failure to pay any amounts due as it relates to such Non-Fundamental Breach). If a Party gives notice to the Breaching Party pursuant this Section 13.7(a) as a result of a Non-Fundamental Breach (or alleged Non-Fundamental Breach) by the Breaching Party and, on or before the end of the cure period therefor, either Party has referred the matter to arbitration pursuant to Section 14.1, in either case where the Breaching Party is in good faith disputing such basis for termination pursuant to this Section 13.7(a), then (i) such cure period will be suspended and (ii) this Agreement will not terminate, unless and until such senior executives resolve the dispute or such court issues a final ruling or award upholding such basis for termination (or unless and until the Breaching Party is no longer disputing such basis in good faith, if earlier). If such court issues a final ruling or award upholding such basis for termination, then the cure period will resume, and the Breaching Party will have the remainder of the cure period to cure the Non-Fundamental Breach. If the Non-Fundamental Breach is so cured within the remainder of the cure period, then this Agreement will remain in full force and effect, otherwise this Agreement will terminate. If such court issues a final ruling rejecting such basis for termination, then this Agreement will remain in full force and effect.

(b)Effect of Termination by Licensee. Upon termination by Licensee pursuant to Section 13.7(a), Licensee will elect to either forfeit all rights granted to it under this Agreement, or, alternatively, elect to continue its license rights hereunder by making all of the same payments that would be required if the Agreement were not terminated as and when such payments become due under Article 8, except that all such payments shall be reduced by ***** from the amounts that are otherwise payable, for the continuation of the license rights granted to Licensee and all future non-financial obligations to Licensor and its Affiliates will immediately cease, other than those obligations which expressly survive any termination of expiration of this Agreement.

(c)Effect of Termination by Licensor. Upon termination of this Agreement by Licensor pursuant to Section 13.7(a), all rights granted to Licensee to the Technology in the Territory will immediately and automatically terminate and revert to Licensor, Licensee will stop recruiting for any ongoing Clinical Studies and will terminate them in accordance with ethical guidelines, and Licensee will promptly assign to Licensor ownership of all data, inventions and rights in any related Patents, and will grant Licensor a an exclusive, sublicensable license under the Joint Patents and Licensee Patents in the Field in the Territory, generated before the date such rights revert to Licensor. The foregoing assignment and reversion of rights is subject to the

payment by Licensor to Licensee of the royalties set forth in Section 3.2(d)(iii) as it relates to any Development Candidate or Product prior to the IND filing and the royalties set forth in Section 3.3(c) as it relates to any Development Candidate or Product after the IND filing, except that all such payments shall be reduced by ***** from the amounts that are otherwise payable.

(d)Transition Assistance to Licensor. In connection with a reversion of rights and assignment in accordance with Section 13.7(d), Licensee will provide such assistance, as expeditiously as possible, at no cost to Licensor, and as may be, and for so long as, reasonably necessary or useful (in Licensee’s sole determination) for Licensor to continue Developing or Commercializing Product throughout the Territory to the extent Licensee, its Affiliates and sublicensees are then performing or having performed such activities, including (i) furnishing to Licensor all safety information owned or controlled by Licensee and (ii) assigning or amending as appropriate, upon request of Licensor, any agreements or arrangements with Third Party contractors to Develop, distribute, sell or otherwise Commercialize Product. To the extent that any such contract between Licensee and a Third Party is not assignable to Licensor, Licensee will reasonably cooperate with Licensor to arrange to continue to provide such services for a reasonable time after termination.

(e) Survival. For the avoidance of doubt, any Article or Section that is referenced in this Section 13.7 shall survive termination to the extent applicable to this Section 13.7.

13.8 Survival. Termination or expiration of this Agreement will not affect rights or obligations of the Parties under this Agreement that have accrued before the date of termination or expiration. Notwithstanding anything to the contrary, the following provisions will survive any expiration or termination of this Agreement: *****.

ARTICLE 14

DISPUTE RESOLUTION

14.1 Arbitration. In the event of any disputes, controversies or differences between the Parties (except for disputes arising from the JRC, which will be handled pursuant to Section 14.2 and only handled pursuant to this Section 14.1 as provided in Section 14.2), arising out of, in relation to, or in connection with this Agreement, including any alleged failure to perform, or breach, of this Agreement, or any issue relating to the validity, construction, interpretation, enforceability, breach, performance, application, or termination of this Agreement a (“Dispute”), then upon the written request of either Party, the Parties agree to meet and discuss in good faith an amicable resolution thereof, which good faith efforts include at least one in-person meeting between the Executive Officers of each Party. If the Dispute is not resolved within ***** following the written request for amicable resolution, then either Party may then initiate arbitration under this Section 14.1. Any Dispute that the Parties do not resolve through amicable resolution will be settled by final and binding arbitration administered by JAMS, Inc.,

the alternative dispute resolution company formerly known as Judicial Arbitration and Mediation Services, Inc., pursuant to its Comprehensive Arbitration Rules and Procedures then in effect (the “JAMS Rules”), except as otherwise provided. The number of the arbitrators will be one. The arbitration will be conducted in New York, New York. The language of the arbitration will be English. Judgment on the award may be entered in any court having jurisdiction. Except as may be required by Law, neither Party may disclose the existence, content, or results of any arbitration hereunder without the prior written consent of both parties.

14.2 Referred from JRC. With respect to disputes arising from matters delegated or referred to the JRC pursuant to the terms of this Agreement, either Party may, by written notice to the other Party, have such dispute referred to each Party’s Executive Officers for attempted resolution by good faith negotiations within ***** after such notice is received. If the Executive Officers of the Parties are not able to resolve a dispute within the ***** period described above, then the Executive Officer of Licensee may cast the deciding vote for the JRC.

14.3 Equitable Relief. Notwithstanding Sections 14.1 and 14.2, each Party acknowledges that its breach of Article 12 may cause irreparable harm to the other Party, which cannot be reasonably or adequately compensated by damages in an action at law. By reason thereof, each Party agrees that the other Party may, in addition to any other remedies it may have under this Agreement or otherwise, seek preliminary and permanent injunctive and other equitable relief from any state or federal court of competent jurisdiction in New York, New York to prevent or curtail any actual or threatened breach of Article 12 that is reasonably likely to cause it irreparable harm. In addition, notwithstanding Sections 14.1 and 14.2, to the fullest extent provided by Law, either Party may bring an action in any court of competent jurisdiction for injunctive relief (or any other provisional remedy) to protect a Party’s rights or enforce a Party’s obligations under this Agreement pending final resolution of any claims related thereto pursuant to the dispute resolution procedure set forth in Section 14.1.

14.4 Governing Law. This Agreement and all disputes arising out of or related to this Agreement or any breach hereof are governed by and construed under the Laws of the State of New York, without giving effect to any choice of law principles that would require the application of the Laws of a different state.

14.5 Patent and Trademark Disputes. Notwithstanding Section 14.1, any dispute, controversy or claim relating to the scope, validity, enforceability or infringement of any Patent or trademark rights outside the U.S. covering the manufacture, use, importation, offer for sale or sale of Product will be submitted to a court of competent jurisdiction in the country in which such Patent or trademark rights were granted or arose.

15.4 No Strict Construction; Interpretation; Headings. The language in this Agreement is to be construed in all cases according to its fair meaning. Except where the context otherwise requires, wherever used, the singular includes the plural, the plural the singular, the use of any gender applies to all genders. The word “or” is used in the disjunctive sense and the word “and” is used in the conjunctive sense.

The term “including,” “include,” or “includes”, whether or not followed by “without limitation” or “including, but not limited to,” or words of similar import, shall be construed to mean in each case including, without limiting the generality of any description preceding such term. The Parties agree that no meaning should be inferred about the use of “without limitation” or “including, but not limited to” in some instances but not others. Unless the context requires otherwise, (i) any definition of or reference to any agreement, instrument or other document will be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein or therein), (ii) any reference to any Laws will be construed as referring to such Laws as from time to time enacted, repealed or amended, (iii) any reference to

any person will be construed to include the person’s successors and permitted assigns, (iv) the words “herein”, “hereof” and “hereunder”, and words of similar import, will be construed to refer to this Agreement in its entirety and not to any particular provision hereof, (v) any reference to the words “mutually agree” or “mutual written agreement” will not impose any obligation on either Party to agree to any terms relating thereto or to engage in discussions relating to such terms except as such Party may determine in such Party’s sole discretion, (vi) all references to Sections, Exhibits or Schedules will be construed to refer to Sections, Exhibits and Schedules to this Agreement, (vii) the word “days” means calendar days unless otherwise specified, and (viii) the words “copy” and “copies” and words of similar import when used in this Agreement include, to the extent available, electronic copies, files or databases containing the information, files, items, documents or materials to which such words apply.

Each Party represents that it has been represented by legal counsel in connection with this Agreement and acknowledges that it has participated in the drafting hereof. In interpreting and applying the terms and provisions of this Agreement, the Parties agree that no presumption will apply against the Party which drafted such terms and provisions.

15.5 Assignment. Neither Party may assign or transfer this Agreement or any rights or obligations hereunder without the prior written consent of the other Party, except that a Party may, subject to Section 13.4, make such an assignment without the other Party’s consent to its Affiliates or to a Third Party successor or transferee to assets of such Party in the Field to which this Agreement relates (such Third Party, an “Acquiror”), whether in a merger, sale of stock, sale of assets or other transaction. Any successor or assignee of rights or obligations permitted hereunder will, in writing to the other Party, expressly assume performance of such rights or obligations. The Technology excludes any Patents and Information Controlled by any Acquiror (or any Affiliate thereof, excluding a Party hereto as a result of such transaction) except to the extent such Acquiror’s Information or Patents are Controlled by Licensor or Licensee, as applicable, or any of Licensor’s or Licensee’s, as applicable, Affiliates, and are necessary for the Development or Commercialization of Product and used in respect of Product in the Territory. Any permitted assignment will be binding on the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of this Section 15.5 is null, void and of no legal effect.

15.6 Performance by Affiliates. Each Party may discharge any obligations and exercise any right hereunder through any of its Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and will cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. Any breach by a Party’s Affiliate of any of such Party’s obligations under this Agreement is a breach by such Party, and the other Party may proceed directly against such Party without any obligation to first proceed against such Party’s Affiliate.

15.7 Further Assurances and Actions. Each Party, upon the request of the other Party, whether before or after the Effective Date and without further consideration, will do, execute, acknowledge, and deliver or cause to be done, executed, acknowledged or delivered all such further acts, deeds, documents, assignments, transfers, conveyances, powers of attorney, instruments and assurances as may be reasonably necessary to effect complete consummation of the transactions contemplated by this Agreement, and to do all such other acts, as may be necessary or appropriate to carry out the purposes and intent of this Agreement. The Parties agree to execute and deliver such other documents, certificates, agreements and other writings and to take such other actions as may be reasonably necessary to consummate or implement expeditiously the transactions contemplated by this Agreement.

15.8 Severability. Each of the provisions contained in this Agreement will be severable, and the unenforceability of one will not affect the enforceability of any others or of the remainder of this Agreement. If any one or more of the provisions of this Agreement, or the application thereof in any circumstances, is held to be invalid, illegal, or unenforceable in any respect for any reason, the Parties will negotiate in good faith with a view to the substitution therefor of a suitable and equitable solution to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid provision; provided, however, that the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions of this Agreement will not be in any way impaired thereby, it being intended that all of the rights and privileges of the Parties hereto will be enforceable to the fullest extent permitted by Law.

15.9 No Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver will be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. The waiver, delay or the failure of any Party to enforce or exercise any term, condition or part of this Agreement at any time or in any one or more instances will not be deemed to be or construed as a waiver of the same or any other term, condition or part, nor will it forfeit any rights, power or privilege to future enforcement thereof. No single or partial exercise of any right, power or privilege will preclude any other or further exercise of such right, power or privilege or the exercise of any other right, power or privilege. To the maximum extent permitted by Law, (a) no claim or right arising out of this Agreement or any of the documents referred to in this Agreement can be discharged by one Party, in whole or in part, by a waiver or renunciation of the claim or right unless in writing signed by the other Party; (b) no waiver that may be given by a Party will be applicable except in the specific instance for which it is given; and (c) no notice to or demand on one Party will be deemed to be a waiver of any obligation of that Party or of the right of the Party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement. Except as expressly set forth in this Agreement, all rights and remedies available to a Party, whether under this Agreement or afforded by Law or otherwise, will be cumulative and not in the alternative to any other rights or remedies that may be available to such Party.

15.10 Relationship of the Parties. Neither Party will have any responsibility for the hiring, termination or compensation of the other Party’s employees or for any employee benefits of such employee. No employee or representative of a Party will have any authority to bind or obligate the other Party to this Agreement for any sum or in any manner whatsoever, or to create or impose any contractual or other liability on the other Party without said Party’s approval. For all purposes, and notwithstanding any other provision of this Agreement to the contrary, Licensor’s legal relationship to Licensee under this Agreement will be that of independent contractor and nothing in this Agreement gives either Party the power or authority to act for, bind, or commit the other Party in any way. This Agreement is not a partnership agreement. Nothing in this Agreement will be construed to establish a relationship of partners, principal and agent or joint venturers between the Parties or their respective employees or Affiliates. Nothing contained in this Agreement shall be construed to create a “separate entity” or “business entity” within the meaning of the U.S. Internal Revenue Code or the regulations thereunder and any foreign equivalents thereto. Neither Licensee nor Licensor will make any statements, representations, or commitments of any kind, or to take any action that is binding on the other, without the prior consent of the other Party to do so.

15.11 English Language. This Agreement was prepared in the English language, which language governs the interpretation of, and any dispute regarding, the terms of this Agreement.

15.12 Counterparts. This Agreement may be executed in one or more counterparts, each of which is an original, but all of which together constitute one and the same instrument. Each Party may execute this Agreement by facsimile transmission or by PDF. In addition, facsimile or PDF signatures of authorized signatories of any Party will be deemed to be original signatures and will be valid and binding, and delivery of a facsimile or PDF signature by any Party will constitute due execution and delivery of this Agreement.

15.13 Schedules. The disclosure of any matter in any Section of or on any Schedule to this Agreement will only be deemed to be a disclosure for the Section or subsection of this Agreement to which it corresponds in number, unless the applicability of such Schedule to any other Section is readily apparent. The disclosure of any matter in any Schedule to this Agreement will expressly not be deemed to (a) constitute an admission by either Party hereto, or (b) imply that any such matter is material for purposes of this Agreement.

15.14 Expenses. Each of the Parties will bear its own direct and indirect expenses incurred in connection with the negotiation and preparation of this Agreement and, except as set forth in this Agreement, the performance of the obligations contemplated hereby and thereby.

15.15 Section 365(n). The Parties acknowledge and agree that the licenses granted by the Parties pursuant to Sections 4.1 and 4.2 and all other rights granted under or pursuant to this Agreement are, for purposes of Section 365(n), licenses of rights to “intellectual property” as defined under Section 101(35A) of the Bankruptcy Code (or analogous foreign provisions), and

that this Agreement is an executory contract governed by Section 365(n) if a bankruptcy proceeding is commenced involving either Party (as licensor hereunder). Licensee, as the licensee of such rights under Section 4.1, retains and may fully exercise all of its rights and elections under the Bankruptcy Code. The foregoing provisions of this Section 15.15 are without prejudice to any rights the Parties may have arising under the Bankruptcy Code or other Laws.

15.16 Third Party Beneficiaries. Pursuant to Section 2.7 of the Head License Agreements, the Parties agree that Northwestern is a third party beneficiary of this Agreement. Except for the foregoing, the Parties do not confer any rights or remedies upon any party other than the Parties to this Agreement and their respective successors and permitted assigns.

Re: Side Agreement to “Northwestern Agreements” in Relation to Purdue Sublicense

Dear ▇▇. ▇▇▇▇▇▇▇:

Reference is hereby made to that certain License Agreement executed on February 10, 2016 and effective as of May 27, 2014, to that certain License Agreement executed and effective on June 17, 2016, and that certain Restated License Agreement amended on September 27, 2016 and effective as of December 12, 2011 (collectively, the “Northwestern Agreements”) by and between Northwestern University, an Illinois not-for-profit corporation with a principal place of business at ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇▇▇ (“Northwestern”), and Exicure, Inc., a Delaware corporation with a principal place of business at ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇▇▇ (“Exicure”).

WHEREAS, pursuant to the Northwestern Agreements, Northwestern has granted Exicure an exclusive license to certain Patent Rights, and a non-exclusive license to certain Know-How (each as defined in the Northwestern Agreements) and other rights (in total, the “Exicure Rights”);

WHEREAS, Exicure intends to sublicense certain of the Exicure Rights to Purdue Pharma L.P., a Delaware limited partnership having an address at One Stamford Forum, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇ of America (“Purdue”) via a “Research Collaboration, Option and License Agreement” between Exicure and Purdue (the “Sublicense Agreement”), upon the execution of which Purdue would become a Sublicensee (as defined under the Northwestern Agreements).

NOW THEREFORE, in order to clarify the consequences to Purdue in the event of a termination by Northwestern of some or all of the Exicure Rights pursuant to Section 10 of the Northwestern Agreements, Exicure, Northwestern and Purdue hereby enter into this side agreement (“Side Agreement”). Unless otherwise expressly stated in this Side Agreement, all

provisions of the Northwestern Agreements and of the Sublicense Agreement remain unchanged and in full force and effect. Unless defined in this Side Agreement or otherwise indicated, all capitalized terms shall have the meanings assigned to them in the Sublicense Agreement.

Exicure, Northwestern and Purdue, each intending to be legally-bound by this Side Agreement, hereby agree to the following:

(a)Northwestern hereby consents and agrees that further to Section 2.7 of the Northwestern Agreements, Northwestern hereby consents to the grant of the sublicenses set forth as follows:

Subject to the terms and conditions of the Northwestern Agreements, Purdue may grant sublicenses of each license granted to Purdue under the Sublicense Agreement with prior notice to Exicure, only to (A) its Affiliates and (B) Third Party subcontractors (including any Third Party manufacturers), and in each case on the condition that Purdue will at all times sell, offer for sale, import, export and otherwise Commercialize Product in Purdue’s or its Affiliate’s name.

(b)Except as set forth in section (a) above, any sublicense of the Exicure Rights by Purdue pursuant to section (a) above shall fully comport with the remaining provisions of Section 2.7 of the Northwestern Agreements (including, but not limited to the requirement to provide to Northwestern notice and a copy of each sublicense agreement within 30 days of execution). For the avoidance of doubt, all obligations of “Licensee” and “Sublicensee” (as those terms are used in Section 2.7 of the Northwestern Agreements) are still in effect.

(c)(i) In the event of a termination of the Northwestern Agreements (A) by Exicure pursuant to Section 10.2 of the Northwestern Agreements, (B) by Northwestern pursuant to Sections 10.3 or 10.4 of the Northwestern Agreements, (C) pursuant to Section 10.5 of the Northwestern Agreements or (ii) the rejection of the Northwestern Agreements in any bankruptcy proceeding pursuant to 11 U.S.C. § 365, Northwestern, after receiving notice of such termination or rejection, shall promptly notify Purdue in writing of such termination or rejections, as applicable. With effect from the date that Purdue learns of such termination or such rejection, as applicable, whether due to receipt of notice from Northwestern or otherwise and if the Sublicense Agreement is in effect prior to termination of the Northwestern Agreements, then, notwithstanding Section 2.7 of the Northwestern Agreements, Purdue may, within thirty (30) days and upon written notice to Northwestern (the “Springing Notice”), automatically and without further required action, assume the rights and responsibilities of Exicure under the Northwestern Agreements, to the extent of the rights granted to Purdue pursuant to the Sublicense Agreement, solely to the extent necessary to allow Purdue to continue to Develop and Commercialize the Collaboration Targets, the TNF-α Target, Development Candidates and Products within the Field of the Sublicense Agreement. Such rights and responsibilities of Purdue as a sublicensee under the Northwestern Agreements shall continue in full force and effect as long as Purdue is not in breach of any of the material obligations applicable to sublicensees under the Northwestern Agreements.

(d)In the event Purdue provides Northwestern with Springing Notice, all of the rights and obligations of Exicure as licensee under the Northwestern Agreements, including, without limitation, the obligations to make all payments required to be made as a sublicense under the Northwestern Agreements shall be transferred to Purdue in their entirety, and Exicure shall no longer have any responsibility with respect to any such obligations as of the effective date of any such termination. For clarity, the scope of the rights and obligations of Purdue that will survive any such termination shall not in any event exceed the scope and limitations of the sublicenses granted to Purdue under the Sublicense Agreement. In the event Purdue provides Northwestern with Springing Notice and the Sublicense Agreement is in effect and Exicure is not in breach of certain of the material obligations applicable to Sublicense Agreement, Purdue shall remain fully responsible for making all payments to Exicure as required under the Sublicense Agreement, but shall be entitled to deduct any payments that are made directly to Northwestern for the continued sublicense rights under the Northwestern Agreements from the payments that are owed to Exicure under the Sublicense Agreement.

(e)Northwestern, Exicure, and Purdue hereby agree that this Side Agreement is and shall be binding on and enforceable against each of Northwestern, Exicure and Purdue in accordance with its terms, notwithstanding any failure by Exicure to perform its obligations under this Side Agreement.

In witness whereof, the parties have executed this Side Agreement by their duly authorized representatives on the date first written above.

Purdue Pharma and Exicure Announce Strategic Research Collaboration

Agreement to Discover and Develop a Treatment for Psoriasis and Other Diseases

Utilizing SNA™ Technology

Purdue Pharma Will Obtain Full Worldwide Development and Commercial Rights to AST-005, as well as an Option to Three Additional Collaboration Targets with Associated Intellectual Property

STAMFORD, Conn. & SKOKIE, Ill., Dec. 8, 2016--Purdue Pharma L.P. and Exicure, Inc. today announced a strategic research collaboration, option and license agreement to discover and develop a treatment for psoriasis, and other diseases amenable to a gene regulation approach utilizing Exicure’s Spherical Nucleic Acid (SNA)™ technology. Purdue Pharma, upon exercise of the options, will obtain full worldwide development and commercial rights to AST-005, and rights to three additional collaboration targets with associated intellectual property.

The lead compound, AST-005, is an investigational, topically-applied SNA that targets tumor necrosis factor (TNF), a pro-inflammatory cytokine shown to be a key mediator of psoriasis. In a recently completed Phase 1 trial, fifteen patient volunteers with chronic plaque psoriasis were treated with AST-005 for ten days. The first trial with AST-005, based on Exicure’s proprietary SNA technology, met the safety and tolerability requirements in patients with mild to moderate psoriasis. In addition to the safety data typically collected from the first Phase 1 trial, pharmacodynamic assessments were performed from the treated plaque area.

Psoriasis is an inflammatory disease that results in red, scaly patches on the skin. Current treatments for psoriasis include biologics, orally administered drugs and a variety of non-targeted topical treatments. The unique ability of SNA constructs allows AST-005 to penetrate the skin when applied topically and knock down the TNF gene of interest.

Under the terms of agreement, Exicure received an upfront payment, will receive an equity investment and could potentially receive development, regulatory and commercial milestone compensation, which together with the upfront payment and equity investment, could total up to $790 million, if all programs are fully developed, as well as royalties on potential sales of the products.

“This long-term strategic collaboration agreement represents a significant expansion of Purdue’s pipeline, and provides us with the potential to further our mission of developing novel therapies for patients with chronic conditions,” said ▇▇▇▇ ▇▇▇▇▇▇, President and Chief Executive Officer, Purdue Pharma L.P. “We look forward to combining Exicure’s SNA technology and deep

expertise in this field with Purdue’s resources and expertise in clinical studies, regulatory affairs and commercialization for the benefit of patients.”

“Given the broad potential of SNA technology, we want to forge long-term strategic relationships with best-in-class companies. As we were looking for a global leader with a proven track record in the development and global commercialization of treatments for patients with chronic conditions, we were very impressed with the Purdue Pharma’s clinical and commercial capabilities,” said ▇▇. ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, Chief Executive Officer, Exicure.

▇▇▇▇▇▇▇▇▇▇ & ▇▇▇▇▇ LLP served as lead outside counsel for Purdue Pharma. Faber Daeufer & Itrato served as lead outside counsel for Exicure.

ABOUT SPHERICAL NUCLEIC ACIDS

Spherical Nucleic Acids (SNA) are nanoscale, spherical arrangements of densely packed and radially oriented nucleic acids. This architecture overcomes one of the most difficult obstacles to nucleic acid based therapeutics: safe and effective delivery into cells and tissues of therapeutic importance without the need for additional physical or chemical methods or components. The SNAs are designed to be extremely potent and highly targeted gene regulation and immune-modulatory agents. SNA™ technology originated in the lab of ▇▇▇▇▇▇▇▇▇ ▇▇▇▇ ▇. ▇▇▇▇▇▇ at the Northwestern University International Institute for Nanotechnology.
